[07:22:29] some connection yesterday drops due to a sudden increse on read connections at s1(db1073) at 9:39
[07:24:05] lag at the same time on s3
[07:25:29] ^9:39 pm, that is 2015-07-23 21:39 UTC
[08:30:18] I've enabled es2004 on tendril, but got 1 error:
[08:30:21] mysql> alter event es2004_codfw_wmnet_3306_usage enable;
[08:30:22] ERROR 1539 (HY000): Unknown event 'es2004_codfw_wmnet_3306_usage'
[09:30:39] MostlinkedPage::reallyDoQuery is not causing any issue (it gets executed on a separate host by wikiadmin), but I wonder if it could be done differently with triggers/column-based engine instead of taking 14 hours to execute
[10:50:44] we had some spikes on connection failures, again I think because of lag on s3
[16:25:48] db1035 just notified of 90% disk space, checking other nodes
